Hi,
I'm new to the forum, I hope here is the right place to bring this topic !

I am working with ecore models, I set the attributes value for one of the models, everything is fine, but one attribute will not appear in the output file:

as it can be seen in the code below, I set 4 of the attributes hard coded before saving the output file, 3 of them work grete, but the one which is the first one does not appear in the output ! the funny thing is that if I change its type to string it works !

the thing is that it was working fine, unless I have added other attributes in its sibling models (that have nothing to do with this one) !
